THE DOHA ROUND AND THE EFFECTS OF THE REDUCTION OF TARIFF AND NON-TARIFF BARRIERS: AN ESTIMATION OF BENEFITS FOR BRAZIL USING A COMPUTABLE GENERAL EQUILIBRIUM MODEL
ABSTRACT The objective of this article is to simulate reductions of tariff and non-tariff barriers, in the multilateral scope of the Doha Round, and to verify the benefits for Brazil. Therefore, a computable general equilibrium model was estimated using the GTAP software, and four scenarios were simulated. The results show that, for Brazil, in the scenarios in which only tariff reductions are incorporated, the primary and agroindustry sectors would be the most benefited. The multilateral reduction of non-tariff barriers to trade (NTB) would favor, especially, the industrial sectors, of greater technological content. Concerning well-being, scenarios incorporating reductions in NTB or combined reductions in NTB and tariffs are the most beneficial for all regions included in the study, with worldwide gains that can reach over $ 1 trillion.
